In 2003, IBM enhanced the complete range of IBM eServer iSeries mid-range servers using OS/400 V5R2. The iSeries Models 800, 810, 825, 870, and 890 provide unprecedented levels of performance for iSeries customers. The 825, 870, and 890 models use the latest POWER4 processors. The lasted PCI-X features are available for the 800, 810, 825, 870, and 890, as well as Models 270, 820, 830, and 840. These features deliver leading edge technology and performance.
Planning an upgrade from an existing AS/400e or iSeries server to a new model can range from upgrading a very simple plug to performing a complex task in the migration process. This IBM Redbook discusses the various topics that are involved in migrating to PCI, the new PCI-X, and POWER4 processor technology. It examines other significant functions such as high-speed link (HSL) and concurrent maintenance capability.
This redbook includes upgrade scenarios to assist with your planning. It explains such upgrade functions as load source migration and migrating in LPAR scenarios. It also describes the tower options that preserve investments in older hardware or that can be used to migrate to new technology.
HSL is the advanced bus architecture that connects systems and expansion units. Learn how this technology was implemented with HSL at V4R5 and enhanced with HSL-2 at V5R1 and V5R2. You can also see how HSL differs from the SPD optical bus. |
